A Closer Look at the Chrome Tone Tremolo
The Tremolo effect is the modulation of the volume (gain) of a signal path. This
effect is common in guitar and keyboards, and a variety of other instruments.
The beating, or volume movements can add life to an otherwise dull
performance.
The Chrome Tone Tremolo uses the same Dynamic and Auto sections found in
the Wah conguration to modulate the gain in its tremolo circuit. For a detailed
description of the Dynamic and Auto sections, refer to the ‘Closer Look at the
Chrome Tone Wah’ portion of this manual.
Tremolo Section
The Chrome Tone Tremolo
section has only two controls
to adjust the Tremolo effect.
• Mix - the amount of dry
(unaffected) signal and wet
(tremolo’d) signal.
• Range - the overall
modulation range from both the Dynamic and Auto sections.
While the modulation of simply volume does not seem like much of an
effect at all, Chrome Tone can take the basic tremolo effect to new levels of
sophistication.
Using the Dynamic section, a new signal envelope can be created (sample
accurate by the way), allowing the Tremolo conguration to act as a transient
design effect. Fast drum hits can be slowly ramped up, or echoed away with a
beat synced MIDI input signal.
The Auto section can not only produce periodic volume modulation, but using
the Spread control, new stereophonic effects can be created.
Guitar players are very used to a tremolo with a slewed rate control - one that
slowly increased or decreases speed, usually over a 2x range. Chrome Tone’s
Tremolo conguration can realize such affects using MIDI input data and the
Dynamic section’s Mod control to change the LFO rate value over time. Even
better, the actual audio can be used to change the LFO rate - an example of
Chrome Tone as a ‘performance effect’.
